‘ chilly t‘u ' my “il ‘chilly start on forecast. a fairly chilly start on monday but a bright one, plenty of sunshine, turning cloudy with spells of rain pushing them from the west. temperature is largely staying in double figures for many of us, and maximum of 12 degrees. through tuesday and wednesday we picked up an easterly north—easterly wind, it will turn colder, we will see milder air replaced with something colder from the east. the chance of seeing snow through tuesday and wednesday. some uncertainty and stay tuned to the forecast. a quick reminder that the clocks going forward, so do not forget to reset your clocks tomorrow. hundreds of thousands of students and campaigners have gathered in cities across america for rallies pushing for tougher gun laws, the protest, called march for our lives, is being led by survivors of a

massacre in parkland in florida, last month, addressing crowds around the country including in washington, dc, vowing to stop at nothing until lasting changes made. they came from across the country, bringing their message from the centre of power to the nation ‘s capital, one of the biggest gun control them and stations in years, pa rents, control them and stations in years, parents, students, teachers, with one unified message, but then end to school shootings. they are marching because it is time for change. i do not want to be a teacher that has guns in my building. no guns in church, no guns in schools, no guns in the workplace. one of those determined to make the march, lauren, she wasjust determined to make the march, lauren, she was just six when 20 school friends died in the shooting at sandy hook elementary school, in 2012. it is fairly depressing. this should have stopped a while ago...!

it has been very consistent. while ago. it's been very consistent since then. america is used to school shootings but the murder of 17 students and teachers at the parklands school in florida on valentine's day has galvanised a new generation to take direct action. parklands students have already affected changes in the law in florida and as the president was heading south to his florida home, stu d e nts heading south to his florida home, students from there came to washington to ask congress to do more. they know it's coming, they know that there if there is no assault weapons ban passed, then we will vote them out. cheering they know that if there is no tightening of the background checks, we will vote them out. they know that if there is no shrinking of magazine capacity, we will vote them out. scenes like this have been replicated all over the country with

marches from los angeles to boston. it's not just confined marches from los angeles to boston. it's notjust confined to america. across the uk, young people marched in solidarity. congress has passed modest measures in the last few days but nowhere near the sweeping reforms these protesters are demanding. gary 0'donoghue, bbc news, washington. tributes have been paid to a french police officer who died saving the lives of hostages in a supermarket siege in the town of trebes yesterday. lieutenant colonel arnaud beltrame was shot by an islamist gunman and later died of his wounds. three other people were also killed. president macron said the he showed "exceptional courage" and died a hero. lucy williamson reports. this attack has become not the story of a gunmen but the story of a hero. arnaud beltrame. the man who made astonishing bravery seem natural, almost routine. flags were lowered to half—mast at his former base today

and at units across the country to pay homage to their colleague and friend. he was remembered here too by those who never knew him. another tribute every few minutes. he is a hero for me because he's given his life, for a lot of people. he knew it was dangerous, what he did, but he did it. the gendarmerie said arnaud beltrame's death was a reminder of their daily commitment to protect the people. for the people themselves, his actions are a defiant response to the country's would—be attackers, a reminder of the best of france. today, the site of so much drama was a chilled and empty crime scene. its car park still littered with the debris of a terrified and desperate flight. inside this building yesterday, arnaud beltrame offered up his life in place of others'.

his mobile phone, secretly connected to colleagues outside, giving the operation a vital edge. his brother told french radio that arnaud had died a hero. translation: what he did was beyond the call of duty. he gave his life for strangers. he must have known that he didn't really have a chance. if that doesn't make him a hero, i don't know what would. his mother said she wasn't surprised at what her son had done. "that's the way he lived and the way he worked," she said. "he used to tell me he was just doing hisjob, nothing more." that's not how it feels today. lucy williamson, bbc news, carcassonne. two policemen have been killed in a car bombing in the egyptian city of alexandria. government officials say the city's security director was the target. his vehicle was passing by when the device went off

and he escaped unharmed, but five others were injured. the attack comes two days ahead of the presidential election. investigators from the information commissioner's office, are assessing material seized during a seven—hour search of the london offices of the company cambridge analytica. the high court had granted a warrant to access the company's data bases and servers. it's part of a larger inquiry into the use of personal data in political campaigning. the former shadow northern ireland secretary 0wen smith says he'll continue to oppose labour's position on brexit. he's been sacked byjeremy corbyn from the front bench for saying there should be a referendum on the terms of any final deal. mr smith believes the party leadership should be speaking out more forcefully about what he sees as the economic risks of leaving the eu. 0ur political correspondent iain watson reports. the show of unity was relatively short lived. 0wen smith failed to topple

jeremy corbyn as labour leader in 2016 butjoined his shadow cabinet lastjune. he was sacked for being out of step on the eu when he called for a second referendum on the final deal. it was a bit of a surprise, not least when other members of the shadow cabinet said similar things and haven't been sacked. we need, at the end of this process, to trust the british people once more to make a final decision on whether they are content with the real terms of brexit. curiously, last november the shadow cabinet member diane abbott told her constituents she'd argue for the right of the electorate to vote on a final deal. but she stayed at labour's top table. why did you sack him? so whenjeremy corbyn went to speak to party activists, i tried to get him to explain. why didn't you sack diane abbott? thank you so much, all of you, for coming. 0wen smith insists he was surprised to be sacked because he says his views are far more in touch with those of the party membership than his leader's.

and certainly a survey of more than 4000 labour party members last year suggested that three—quarters of them wanted a second referendum on the final deal with the eu. but most of the activists i spoke put tight—lipped loyalty ahead of any policy concerns. i think we need unity to beat the tories. is he right to sack 0wen smith over europe? no. and it's perhaps a measure ofjeremy corbyn's grip on his party that he sacked someone with pro—eu views swiftly without causing a serious split. iain watson, bbc news, westminster. cambridge have beaten oxford in both university boat races. the light blues won convincing victories on the thames in the men's and women's events. john watson has all the details. the traditional duel on the thames.

under overcast skies, a battle for clea rwater. cambridge started under overcast skies, a battle for clearwater. cambridge started on the south side and soon had the pick of it. calm waters and calm heads, building a lead they would never relinquished. cambridge seem to be into a period of dominance. four was of the crew powered cambridge to a course record last year and their return should an era of light blue dominance with back—to—back wins for the first time in 19 years. after defeat to oxford last year, could the cambridge crew in the men's race match that performance? go! they started strongly. with the lead comes the advantage of plotting the best course, the men's crew demonstrating power and control as they took the lead. with the tallest man to compete in the boat race at six feet ten, the levers to keep them there. cambridge taking the 2018 men's boat race. emphatic victory. today, this stretch of the thames belongs entirely to

cambridge. john watson, bbc news. that's it. there's more throughout the evening on the bbc news channel, and i'll be back with the late news at 10:10. now, how should hospitals treat homeless people? they are admitted for emergency treatment many more times than the average patient, and stay on average twice as long. but often, they are simply discharged back on to the streets. 0ne charity wants to change that. it started in london and is expanding across the uk. dougal shaw reports. meet gary spall. he slept rough in london for more than a decade. in that time, he had multiple acute health problems. he was in and out of this central london hospital. typically, he was discharged back onto the streets. this spot is where i used to bed down. it's horrible.

in winter, even worse. how did you feel when you made the five—minute walk out of hospital back to this? it's not a good place to recuperate. really depressed. but thanks to the pathway charity, the nhs became a way to save gary. they made contact with him during a stay in hospital and used it as a chance to turn his life around. now he has a home and a beloved pet dog, lola. the charity helps 3,000 homeless people each year, operating in 11 hospitals across the uk, like this one in east london. it assembles a dedicated team to help the homeless. this includes a gp, a nurse, an occupational therapist and crucially, a care navigator. he's trusted by homeless patients because of his background. sometimes we'll get a patient who says to me "you don't know what it's like to be on the street and be homeless," and i can turn round and say i do understand what that feels like. i've been through the system. i have been homeless. gavin has to first locate homeless people who have been admitted to hospital.

this is the charity's chance to stage an intervention to turn lives around. the pathway team addresses underlying health issues, but they also sort out immediate problems like getting fresh clothes, and help to find housing after leaving hospital. the team hosts a weekly meeting where representatives from housing associations, local hostels and the police can share knowledge to sort out individual cases. this might seem like a lot of work in a stretched health system, but the medical director of the pathway charity says this approach makes sense for hospitals. we can reduce the amount of time people spend in hospital and the need for them to come back to hospital again. so the net result is reducing the stress on the nhs. if not for pathway, i don't think i would be here now, alive, and everything is going good now. dougal shaw, bbc news. now on bbc news, it's time for click. not everyone is happy

about the rise of the robots. this week, we will meet the people whose livelihoods are under threat. the robots, they go for ourjobs. and those who are doing something about it. including people who might have thought that theirjobs were safe. and we start with those who deal with the biggest things on water. this is how stuff moves around the world. your car, your tv, your phone. they all arrived in a shipping container, one of millions each year stacked on gargantuan ships and sailed from where they are made to where they are sold. 0ffloading these containers

at ports across the globe is a complicated task as they are lifted from the ships, moved to the land and then, when the right ride arrives, they are loaded onto lorries to be driven across the mainland. but at europe's busiest port, rotterdam and its third busiest, hamburg, something new is happening. some of the cranes here don't have drivers. and some of the lorries don't have cabs. these are europe's first robotic ports. so what we've got here is a mixture of remote control and completely autonomous machinery and basically, there are no humans in that little bit at all. there is a very strict rule here. human dock workers do their work outside the red line and inside, everything is completely autonomous.

ports across the world perform this graceful ballet of stacking and unstacking, but at two terminals at rotterdam and this one at hamburg, it's a dance that humans aren't allowed take part in. so what happens is, there is a human controlling the crane that pulls the containers off the ship and then loads them onto the central platform and then the human—controlled crane goes and gets another container from the ship. another crane comes along and pulls the container from that platform and loads it onto these trucks. that crane is autonomous. and so are the lorries. while the world is still waiting for the mythical self—driving car, these trucks are already making their way around the ports transporting containers from crane to crane.

buried in the tarmac are thousands of little tiny transponders bleeping away, broadcasting special id numbers. and that's how these trucks know where they are to within a few centimetres. and of course, that makes this a very simple environment to drive around, with a guide track taking them from a to b to c and no unpredictable human hazards. they don't even need sensors to see what's around. the only reason that they need humans in charge of the cranes on this side is because there are humans on the ship and so the law says you can't let computers swing containers around when there are humans. so if there weren't people on the ship, the computers could control this crane as well. it's the same story at the other side of the port. the only thing the autonomous cranes aren't allowed to do is lower the containers onto the lorries because there are human drivers nearby so that part is done by a human crane operator, but from an office nearby.

i mean, it's all very impressive. it looks really cool, but there is a flipside to this which is every one of those trucks that's driving around ten years ago would have had a driver and now it doesn't. and there are no crane operators in the middle section either. so while we are looking at the future of work here, we really need to look about the future of the workforce as well. and the workforce at rotterdam has spoken. in 2016, 3,600 workers walked out to protest at increasing automation at the port. niek stam is the union official for ports.

he says the dockers know they can't fight automation, but he does warn that as fewer and fewer human workers earn wages, there will be less money paid back to the state through income tax. so who is paying them at the end? if the robots take over ourjobs, who is then paying the tax? that's why i said it is time to discuss about robot tax. we still need roads, we still need trains, we still need schools and hospitals, so somebody has to pick up the bill. so if we can have an income, say, 20 hours working week, we also have a separate income from the social benefits, paid by robots. i mean, if they don't like human beings anymore, that's fine. then we start fishing. but we want also an income. as a result of the strike in 2016, the port authority agreed not to cutjobs, and because the economy is buoyant at the moment,

so far these workers are doing the same work in other terminals at the ports. the port of rotterdam told us that although: niek, though, is not convinced everyone will want to retrain. we still need jobs for people who are low educated, that like to work, like to be a comrade on the working place. they still want to work with their hands. what's wrong with that? battersea power station.

one of the uk's most ambitious restoration —— one of the uk's most ambitious restoration projects. at 42 acres, it's the largest construction site i have ever visited, and the race is on to complete refurb of this grade two—listed landmark by 2020. there are 2,000 skilled contractors here working around the clock. since work began five years ago, over 30 kilometres of scaffolding has gone in to rebuild the station's chimneys and painstakingly restore its 7.5 million bricks. it is no surprise that some of the more interesting work to automate the construction industry is happening in san francisco, where dave lee have been to find out more. look, don't tell anyone, but i have been trying to earn a few extra dollars — which is why some days you can find me here, in this construction site. there is a ton of work to be done, but you know what? i don't care, because it is

the end of my shift. i am really not cut out for the construction industry, but that's ok, because thanks to companies like built robotics, maybe i don't have to be. their autonomous system allows this hulking great thing to get to work without a human driver. it can be left alone to get on with the task at hand, which in this case is flattening out the land. it is fully autonomous. what that means is basically, you load in plans for what you want your finished product to look like, and the machine looks at the plans, figures out how to navigate around the site in order to accomplish the work, and then sends commands to the on—board electronics on each machine, so they can go out there and do the work. noah is a former google engineer and he uses much of the same

technology that can be found in that company's self driving car. but he says his vehicle has to consider many more factors when going about its work. so it is a lot of nuance around how different types of soils interact with the blade, how the tracks spin and slip as you move around a rough jobsite, that is really the hard part and that is what we focus on. it is notjust here on the ground at construction sites where autonomy is changing how things work. for a fuller picture, you need to look to the skies. one of the biggest challenges with construction, particularly big projects, is knowing what is going on and where. skycatch, also based in san francisco, has created what is essentially a foreman in the sky, a drone system that can analyse sites with incredible detail and share its findings almost immediately. it would normally take weeks to survey an area as big as this, costing money and of course time. now a detailed scan can be

captured in just 15 minutes. these are becoming real tools now. before we had cameras, we took video, photos, now we can do real work with them. the technology we put inside these machines can give you data that can be immediately used on the field. at any given point construction sites are changing all the time. you may know what is going on five minutes ago, five minutes later it is completely different. the success of this company is of course good news for companies that are trying to cash in on the increased automation of construction sites. but for the millions who make their living, a good living, getting stuck in on sites around the world, life is going to change. so yes, thejobs will be reallocated. i think we will be spending more time planning, on making sure that things are done on time, but it will also have other really awesome effects. buildings will be built in days. it will be a lot more affordable to build a highway,

a lot more affordable to build a home. so we believe that this will also help equalise how quickly people have access to homes. that was dave lee in san francisco. that's it from us here at battersea power station. this is the short cut of the show, the full—length version is up on iplayer to watch now, and we have loads of backstage photos on twitter as well. thanks for watching and we will see you soon. feeling very springlike for many of us, tomorrow seen

the lion's share of the sunshine, good spells of sunshine and just the risk of one or two showers, particularly for north and west. there have been a few showers in the north—west, they will persist through the night, wintry over high ground. clear skies moving south—east, holding onto cloud and outbreaks of light rain and drizzle, one 01’ outbreaks of light rain and drizzle, one or two patches of missed, not quite as cold in the south—east, way from that, chance of a touch of frost. milder start, that cloud will thin and live. more in the wake of brightness developing, good spells of sunshine, perhaps a view showers for north west scotland, which could be wintry over high ground. not feeling too bad with highs of 12 celsius and light wind. for i leave you, the clocks are going forward as we move through tonight, for the beginning of british summer time tomorrow. —— before i leave you.

this is bbc news. the headlines at seven. hundreds of thousands of people across america join student—led protests to call for tighter gun controls the sound of silence — parkland school survivor emma gonzalez stood before the crowd for 6 minutes and twenty seconds. ina in a little over six minutes, 17 of oui’ in a little over six minutes, 17 of our friends were taken from us, 15 we re our friends were taken from us, 15 were injured and absolutely everyone in the douglas community was forever altered. he fell as a hero — tributes to the french policeman who died after saving the lives of hostages. 0wen smith says he'll continue to argue for change to labour's position on brexit, after being sacked from the party's front bench. a warning that the headlights on modern cars are dazzling drivers.
